DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

SDK Mode-Aware Error Messages

Error messages for PDF and image handling now provide context-appropriate guidance based on whether Claude Code is running in SDK mode:

  • PDF too large:
  • Interactive: "PDF too large. Please double press esc to edit your message and try again."
  • SDK mode: "PDF too large. Try reading the file a different way (e.g., extract text with a CLI tool)."
  • Password-protected PDF:
  • Interactive: "PDF is password protected. Please double press esc to edit your message and try again."
  • SDK mode: "PDF is password protected. Try using a CLI tool to extract or convert the PDF."
  • Image too large:
  • Interactive: "Image was too large. Double press esc to go back and try again with a smaller image."
  • SDK mode: "Image was too large. Try resizing the image or using a different approach."

Hi8() at line 278470, Di8() at line 278475, Fi8() at line 278480 (contain d2() SDK mode check)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
